When the controller drives the servo motor 4 to start, the spindle component 3 can drive the chuck 507 to rotate synchronously through the transmission of the transmission belt 6, so that the workpiece can be rotated 360 degrees, and the tool can realize multi-faceted turning.

[0025] exist Figure 1 and Figure 3In the figure, the spindle component 3 is located at the top of the spindle box, and there are two groups of roller linear guides 501, and the number of roller linear guides 501 in each group is two.

[0026] exist Figure 2 and Figure 3 In the figure, there are four Z-axis support plates 504, which are slidably connected to four roller linear guides 501 respectively.
